IMPROVED LOOSE-JOINT BUTT-HINGE.

TO ALL WHOM IT MAY OONOERN:

Y Be it known that I, MARSHALL PERRY, of the State, city, and county oi' New York, have invented a new and useful improvement in Reversible Loose-Joint Butt-Hinges;V and I do hereby declare that the following is a full and 'clear description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon.

I `The nature of my invention consists in constructing the hinge in the manner described, that it may be used at pleasure either as a right or left-hand hinge. t

To enable others to make and use my invention, I will proceed to describe its construction and operation.

The hinges may be castor made of wrought metal, when made after my invention, in any ofthe well-known ways now practised.

Figure 1 represent-s a side view of the part having'the pintle.

Figure 2, a vertical cross-section of the same.`

Figure 3, a side view of one side of that part having the sockets for thc pintle to enter, the position of the sockets onthe opposite side being shown in dotted lines. Y

VFigure 4, a top edge view of the same.

Figure 5, wperspective of the parts united, the extra sockets'being shown in dotted lines.

rIhe part having'the' pintle is cast or otherwise formed, as usual. The other halt` of the hinge is provided with two sockets to receive tho pintle, and these sockets are ou opposite sides and edges of the plate, and one at the bottom and the other at the top of the said plate. The knuckle for holding the pintle, in this instance, projects squarely and evenly from the edge of the halt' of the butt. I do not, however, confine myself to attaching it centrally to theedge, That portion of the side edge of the hinge above each socketed knuckle is not y cut away, as is usually the case, but is rabbeted or grooved out to receive the rounded portion of the knuckle A containing the pintle, forming for the same a support and astop. I do not desire to limit myself to projecting the soeketed knuckles entirely from the side ofthe plate, as shown in figs. 1 and 2, as I contemplate the knuckles might occupy, with respect to that portion of the hinge, the position shown of the knuckle having the pintle, and that portion of the edge of the plate might be cut away above each respective socketed`knuckle, instead of being groovedas represented. The holes for the screws are countersunk on both sides.

The gist of my invention lies in placing the socketcd knuckles, one at the bottom and the other at the top side of the plate, and using the same with a plate having a knuckle and pintle; The plate carrying the pintle is screwed to the casing, and if the door is to swing open round to the right, the plate carrying the-soeketed knuckle is put on so that the socketed knuckle will project from the plate when on the edge ci' the door, at the upper right-hand side of the plate, the other knuckle, at the back and lower sidebeing let into the door. If the door is to swing open to the left the sockcted knuckle should project from the plate when on the edge of the f door, at the upper left-hand side, the other knuckle, projecting at the back and lower right side, beingllet into thc door.

Having described my inventionuwhat I claim as new, and desire to secure by Letters Patent, is- A right or lc- Et-hand hinge composed of two plates, one having a single pintle-carrying knuckle, and the other having two socketd pintle-receiving knuckles, one projecting fromthc top, and the other from the bottom of said plate, but at' opposite edges, substantially as and for the purpose set forth. i
